(a−b)+a+(a+b)=45
⟹3a=45
a=15
a(a+b)=300
⟹15(15+b)=300
⟹225+15b=300
⟹15b=300−225
⟹15b15=7515
b=5
a−b=10⟹a=15⟹a+b=20
The three numbers are 10, 15, and 20.
Proof:
10+15+20=45✓
Answer: V = 48
Step-by-step explanation:
V = lwh
Height is 12
Knowing the base has an area of 4, we can assume that the prism either has a length of 2 and width of 2, or length of 4 and width of 1. Either way will provide the same answer.
Now we can solve.
V = lwh
V = (12)(4)(1)
V = (12)(4)
V = 48
